河北省南宫市奋飞中学2018届高三英语复习课件虚拟语气 (共34张PPT).ppt

掌握虚拟语气的几种主要形式 1.（1）条件从句+主句（一）含蓄条件句 （二）时间错综句 （三）虚实错综句 （2）虚拟中的倒装 2. wish, as if, if only 的虚拟形式 3. would rather .的虚拟形式 4. It is time that 的虚拟形式 5. 名词性从句中的虚拟语气 一：虚拟语气在条件状语 从句中的用法。 时间 If 从句的谓语形式 主句的谓语形式 现在 过去 未来 过去时（were） 过去完成时 Would/could/should/ might +V.（原） Would/could/should/ might+have+p.p. 1.过去时 2.should+V. 3. were to do would/could/should/ might +V.（原） If I were a student, I would make good use of the time . 表示与现在事实相反 If I had listened to the teacher carefully , I would have passed the exam. 表示与过去事实相反 If we had another 7-day holiday, all of us would be more happier. 表示与将来事实相反 （一）、含蓄条件句 含蓄条件句就是虚拟条件暗含在短语或上下文中，从句不表现出来。这时，必须根据句中表述的意义以及某些特定的信息词，来判断此时须采用的形式。常出现 But for ,without , otherwise 1.Without electricity, human life ______ quite different today. A. is B. will be C. would have been D. would be 2. I am busy now. otherwise, I _________help you. (转换成if条件句) If I were not busy now, I would help you. Without electricity = If there were no electricity would （二）、时间错综句 从句与主句或上下文所表述的时间不一致。在这种情况下，我们切不可照搬某种形式，而应该按照句中所表述的时间关系，再选择相应的虚拟形式。例如： If you had worked hard yesterday, you would be tired now. 1.If the flower had been watered, it ______ now. A. wouldn’t die B. is dead C. had been dead D. will not die 2.If his television set had not been stolen yesterday, he ______ TV now. A. would watch B. would have watched C. would be watching D. is watching （三）、虚实错综句 所谓“虚实错综句”是指虚拟现象与客观事实错综交织在一起的句子。这就需要我们细心判断哪一处是虚拟语气，哪一处应使用陈述语气。 1.They ______ earlier, but the car wasn’t ready. A. can have left B.may have left C. will have left D. might have left （2）.假设条件虚拟倒装。 条件从句中有should， were， had三个助动词可以把if省略，并将这三个词提至句首。 If I were you, I would give it up. Were I you, I would give it up. If it were not for your advice,
